摘要： The optical ring resonance filter design using different double-ring structures with an inserted BG is proposed in the present article. A high-index contrast grating is integrated with the filter models and is configured as an individual cell transfer function. Each double-ring design is embedded with a grating element, and by transforming it into an SFG representation from the waveguide layout, the Z-domain modelling is performed. The Z-transform approach is an effective tool in modern-day optical communication, which also finds its use in spectral analysis. The establishment of the optical ring resonance is also achieved, and the Opti-FDTD software served the purpose. The frequency responses of the filters are obtained in the MATLAB environment. The spectral profiles of the filters are almost identical and obtain an FSR bandwidth of 27.09 THz, which is a great advantage. Other than the FSR bandwidth, performance parameters like transmission peak, sidelobe magnitude, and SMSR magnitude are also measured. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.

摘要： This communication showcases teaching strategies implemented in a Transport Phenomena course at the undergraduate level to understand heat transfer by conduction, incorporating elements of STEM education (Science, Technology, Engineering, and Mathematics). The educational proposal focused on designing four STEM Workshops under the design-based research methodology. In the first one, interactive simulations were designed using the PDEtool of MATLAB so that the student could visualize the heat transfer phenomenon using color palettes to build the corresponding isotherms. In the second workshop, a hands-on laboratory kit based on ARDUINO was designed in which the student could experimentally validate the studied phenomenon, while in the third workshop, MATLAB was used to visualize the analytical solution of the heat equation. Finally, in a fourth workshop, a detailed mathematical modeling and simulation of the phenomenon was performed using COMSOL. The didactic strategy was evaluated in groups of Transport Phenomena in 2020 (n=42), =42), 2021 (n=40), =40), 2022 (n=21), =21), and 2023 (n=32) =32) terms for engineering students. Through its application, the students understood the basic concepts of computer-assisted process simulation and improved their skills, allowing the implementation of the B-Learning model in the Transport Phenomena course. In all cases, teaching materials, "ready-to- use" codes, and step-by-step instructions have been provided. Readers are invited to use the tools to contribute their evaluations.
